Question

a/b =0.8 and 6a+ 11b=79​

Answer 1

If you want me to solve a and b,then here is the answer.
....
a/b = 0.8=8/10

=>10a=8b

=>10a-8b=0-----(1)

6a+11b=79-----(2)

(1)×3=>30a-24b=0

(2)×-5=>-30a-55b=-395

=>-79b=-395

Hence,b=5.
..........
(1)=>10a-8(5)=0

=>10a=40

Hence,a=4.
....
Hence,a=4,b=5.
